Answer #1

Probability that a patient is white : P(A) = 67.4/100 = 0.674

Probability that a patient is female : P(B) = 43.2/100 = 0.432

Probability that a patient is both white and female : P(A and B) = 34.7/100 = 0.347

By Addition theorem of probability,

P(A or B) = P(A) + P(B) - P(A and B)

Probability that a patient is EITHER  white OR female = P(A or B) = 0.674+0.432-0.347 = 0.759

Percentage of patients that are EITHER white OR female = 0.759*100 = 75.9

Probability rule : Addition theorem of probability
